An autopilot system whereby if one A/P fails cannot carry out an auto-land is called fail_ _ _ _:
a. passive.
In a yaw damper:
d. rudder is moved in proportion to rate of angular velocity.
“LOC ARMED” lights up on the annunciator, this means:
b. localiser armed and awaiting capture.
What is the most basic function of an autopilot?
c. wing leveller
What does the autopilot pitch / rotate around?
a. centre of gravity
During a semi-automatic landing:
a. the A/P is disengaged at DH having followed the ILS.
If only a single A/P is used to climb, cruise and approach; following a failure:
d. it is fail safe and will disconnect.
In heading select the autopilot delivers roll commands to the controls to bank the aircraft:
1 proportional to TAS, but not beyond a specified maximum.
2 Set bank of 27 degrees.
3 Set bank of 15 degrees.
4 Proportional to the deviation from the selected heading.
